In a bucket, 16.4 g of oven dried pulp is dispersed in 4000 mL of water. What is the consistency in the bucket (g/L and in %)? If 700g of the slurry is taken to make a square handsheet that is 20.3 cm x 20.3 cm, what would be the basis weight of the handsheet in g/m^2?
Assume you know that the consistency of a slurry is 0.46%. How much of the slurry is needed to make a 3 gram handsheet (in ml)?
450 grams of a pulp slurry is filtered over a filter paper in a Buchner funnel and weighed after drying. The following is found:Weight of bone dry filter paper = 0.25 grams. Bone dry filter paper and pulp = 6.55 grams. What is the consistency of this pulp slurry?
